Description

Technical Field

[0001] The invention relates to the field of medical devices, and in particular to a device for detecting diabetic peripheral neuropathy. Background Art

[0002] Diabetes is a metabolic disease characterized by high blood sugar. Symptoms such as diabetic peripheral neuropathy often appear too late. Long-term high blood sugar can lead to microvascular, macrovascular and neuropathy. About half of diabetic patients will develop distal symmetrical polyneuropathy, with symptoms including hyperalgesia, numbness of the extremities and loss of sensation, especially painless neuropathy. Due to the loss of protective sensation (pain, touch, position sense, etc.), small and difficult-to-detect skin injuries on the feet often cause foot ulcers to appear and worsen, leading to uncontrollable amputation and disability. If not diagnosed and treated in time, it will seriously affect the patient's quality of life.

[0003] At present, the major guidelines for screening of diabetic peripheral neuropathy recommend that screening should include vibration sense, pressure sense, pinprick pain, and tendon reflexes, and various tools are required, including tuning forks, 10g nylon threads, pins, and percussion hammers. Existing examination methods require various tools, many of which are neurological examination tools. The inspection site of diabetic neuropathy is unclear. Because there are many instruments, it is extremely inconvenient to carry, and it is easy to miss or lose them. They need to be replaced many times during use, which is troublesome and has a certain adverse effect on actual use. Therefore, it is necessary to provide a peripheral neuropathy examination tool that is easy to carry and has integrated functions. Summary of the invention

[0004] The present invention is intended to provide a diabetic peripheral neuropathy examination device, so as to provide a peripheral neuropathy examination tool which is easy to carry and has integrated functions.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a device for detecting diabetic peripheral neuropathy, comprising a tuning fork portion and a detection hammer portion, the tuning fork portion comprising a fork handle and two fork arms arranged on the fork handle, the detection hammer comprising a hammer rod portion and two hammer head blocks detachably connected to the hammer rod portion, the two hammer head blocks are respectively slidably arranged on the two fork arms, and locking pieces are arranged on the hammer head blocks.

[0006] The beneficial effects of the present solution are as follows: through the above arrangement, on the one hand, the hammer head block in the present technical solution is slidably arranged on the fork arm, and the hammer head block can be detachably connected to the hammer rod part. When it is necessary to perform a tendon reflex examination on the patient through a percussion hammer, the hammer head block and the hammer rod part can be connected to form a percussion hammer, which is convenient for medical staff to perform percussion detection on the patient's Achilles tendon, and the tuning fork can be struck with the hammer rod part to make the tuning fork vibrate; on the other hand, the hammer head block is slidably sleeved on the fork arm, and a locking piece is provided on the hammer head block, and the position of the hammer head block on the fork arm can be adjusted by the locking piece and the sliding hammer head block. The frequency of a conventional tuning fork is fixed, and the course of disease or degree of sensory failure of some patients being tested are not the same, and there are differences in the vibration perception of the tuning fork detection. Through the above arrangement, medical staff can adjust the frequency of the tuning fork by adjusting the position of the hammer head block, so that the tuning fork can be suitable for patients with different courses of disease, and the patient's perception of vibrations of different frequencies can be more accurately measured, which is helpful to establish a corresponding relationship between the vibration frequency and the stage of diabetic neuropathy, and improve the accuracy of diagnosis. At the same time, the hammer rod part in the technical solution can be connected to the two hammer head blocks. When in use, the locking piece can be unlocked and then the hammer rod part can be pushed, which can simultaneously drive the two hammer head blocks to slide along the fork arm, so that the sliding distance of the two hammer head blocks is the same, ensuring that the counterweight is at the same height when striking the tuning fork later, ensuring that the same frequency resonance occurs between the two fork arms, and the two hammer head blocks are linked by the hammer rod part to slide in the same direction and at an equal distance, ensuring that the mass distribution of the two fork arms is symmetrical, avoiding vibration mode distortion caused by unequal distance.

[0007] This technical solution integrates tuning fork detection and tendon reflex test functions, reducing the number of inspection tools that need to be carried, solving the problems of a wide variety of traditional tools, easy omissions and inconvenience in carrying, and improving the convenience and practicality of clinical examinations; the overall structure is compact, and the design not only meets the requirements of portability, but also takes into account the convenience of operation during the examination process.
